SYSTEM.

SPECIFICATION forming-part of Letters Patent'No. 632,958, dated September 12, 1899.

Application filed March 14, 1898- To all whom, it may concern:

Beitknown that WQELIJAH M. BOSLEY and WILLIAM WURDAoK-, ci tizens of the United; States, residing at St. Louis, State of Missouri, have made a certain new and useful Im provementin Heating Systems, of which the follow-; in g is a full, clear, and exact description, such? as will enable others skilledin the art to which it appertains to make anduse the same, refer-i ence being had to the accompanying draw ings, forming part of this specification, in which Figure l is a cross-sectional view through a radiator employed in ourimprovedheating system. Fig. 2 is a longitudinal sectional view'of the sanie. Fig. 3 is a view of a .portion of our improved radiator, illustrating-the rear end thereof. Fig. 4 isa front end eleva-' tional view, and Fig. 5 is a diagrammatic illus-i tration,.of a heating system :in which our improved radiator is employed.

This invention relates to a new and useful improvement in heating systems, the object being to construct a radiator foruse as a hotwater or steam radiator in;an ordinary heating system,in which radiator gases or oil may be employed as fuel when the radiator is used as an individual heater.

In the event thatsthe radiator is used in a heating system suitable pipe connections may be made, as are well understood, and, if desired, pipe connections maybe madeto another radiator located in the same room or inan adjoining-room, whereby when gas or oil is used for fuel the radiator willheat one or more rooms. \Vhen the radiator is used in :Fig. 5, in which aboiler or furnace isused, if it is notdesired to-start said boiler orfurnace and circulate waterthrough the entire system any individual radiator may be heated, which individual heating of the different radiators may also be employed to advantage to assist the boiler when rapid heatingis required, as when the fire in the furnace is low or in extreme cold weather.

Thisradiator may be used .as a direct indirect radiator-that is,when the local burner is not in operation a fresh-air .pipe from the outside connected to the combustion-chamber opened.

and admits the same after it has been warmed into the room. By this arrangement the radiator can be used alternately as a primary heater or as a direct indirect radiator.

1n the drawings, A indicates the different sect-ions of our improved radiator, which are joined together in the usual manner, said sections being connected at top and bottom for the circulation of water, there being also three water-columns provided. Arranged longitudinally through the lower portion of these sections A is a combustion-chamber B, which opens out at each end, one end being closed by a cap 0, carrying a door 0, said cap leading the products of combustion to a returnfiue.D, which is somewhat smaller than the chamber B, said flue D also having a cap E at its opposite or front end, which leads to a parallel flue .F, from the opposite or rear end of which leads a pipe G. The front end of combustion-chamber B is closed by a cap II, carrying a damper H.

I indicates a burner located in the combustion-chamber B.

If it is desired to individually heat the radiator or use the same as a local heater, the

burner is lighted and the draft-openings in the front end of the combustion-chamber The products of combustion pass rearwardly into and through the return-flue D and into and through the return-flue F, whence they are led by pipe G to the chimneyor to the exterior. The reduced diameter of pipe G is sufficient to carry off the spent gases andalso to cause the heat to linger in the fines, whereby the best results are obtained. lief-valve .L-which valve discharges intopipe The radiatoras thus used has a re- G. Thus it will be seen that the burner when lighted will heat the water contained cold water sinks to the bottom, where-it will remain until sufficiently heated to rise, said water then heatingthe radiator and causing the same to heat the surrounding atmosphere,

as is well understood.

We will now describe the system illustrated in Fig, 5, wherein our improvedradiators are employed in an ordinary hot-water system.

1 indicates a boiler and furnace which is generally located in the lower part of a system, as in the basement of a building, said boiler, and, in fact, the whole system, being provided with an expansion-tank 2, communicating with said boiler through the medium of a pipe 3. This expansion-tank is located above the highest point of the system and is designed to compensate for the expansion or contraction of the Water in the system, as is usual in systems of this kind.

4 indicates a pipe leading from the top of boiler 1 to the lowest point of the radiator 5, located, preferably, in the first room above the basement, said pipe at being provided at a point near to its entrance to the radiator with a valve (5, controlling the admission of water thereto.

7 indicates a pipe which is practically a continuation of pipeet and is attached to the lowest point of a radiator 8 and is shown as being located in the second room above the basement, said pipe 7 being provided with a valve 9, located near the radiator S and controlling the admission of water to said radiator in like manner to valve 6 to the radiator 5.

be reheated.

11 indicates a pipe connecting the upper end of radiator 5 with the lower end of radiator 8, said pipe being provided with a valve 12, designed to open or close communication between said radiators when it is desired to use the lower radiator as a generator for the upper radiator or use said lower radiator separately.

13 indicates a pipe or air-duct, one end of which communicates with the combustionchamber B of the radiator and the other end of said pipe communicates with the atmosphere.

l/Vhen it is desired to heat a room by direct indirect radiation, the door C of the radiator is raised, as shown in the upper radiator in Fig. 5, and the burner in said radiator is not lighted; but the water in said radiator is heated either by the burner in the lower radiator or by the furnace and boiler, as is obvious. When said water in the upper radiator is heated, the cool air from the exterior will be drawn into the chamber wherein the burner (not in use) is located and will become heated and pass out through the openings in the damper-plate H at the front end of the radiator into the room. hen it is desired to use the burner in this radiator for a local heater or a generator for other radiators, the door 0 is closed, which will then act as a check-valve, preventing the cool air from the exterior from entering the radiator, the same being undesirable when it is necessary to use this burner. When this radiator is used as a heater, the door 0 is closed, as

said door will yield in an outward direction to prevent the force of the explosion having injurious effects on the radiator.

The introduction of the flues B, D, and F into the radiator will not materially change the shape of the radiators now in use, as the same pat-terns employed for making standard radiators can be used for the radiator shown in the drawings with slight changes.

It'will be observed from a glance at Fig. 2 that we are enabled by admitting air in the front end only of the combustion-chamber to gradually heat said air before it has commingled thoroughly with the fuel, thereby greatly increasing the combustion, which would not be the case should cold air be admitted to the combustion-chamber at various points.

Ve are aware that minor changes in the construction, arrangement, and combination of the several parts of our radiators can be made and substituted for those herein shown and described without in the least departing from the nature and principle of our invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a radiator, the combination with a series of vertically-arranged sections arranged side by side and communicating with each other, each of said sections being formed with openings which, in the assembled radiator, are alined to form a horizontally-disposed combustion-chamber and a horizontally-disposed draft-fiue within the radiator proper,

and a connection on the end section of theradiator between said combustion-chamber.

and said draft flue, substantially as described.

2. In a radiator, the combination with Vertically-disposed sections arranged side by side and communicating with each other, each of said sections being formed with openings, which, in the assembled radiator, are alined to form a horizontally-disposed combustionchamber and a horizontally-disposed draftfiue within the radiator proper, a connection on the end section of the radiator between said combustion-chamber and said draft-flue, a burner in said combustion-chamber, and a draft-regulating device at the front end of said combustion-chamber, substantially as described.

3. The combination with a heating system said radiators maybe employed as a primary heat-generator, and doors in the pipes 13, which are opened when the radiators are used as direct indirect radiators, said doors being closed when the burners are in operation, substantially as described.

4:. The combination with a heating system, in which is included a plurality of radiators and a source of hot-water or steam supply, there being suitable pipe connections, said radiators being formed with combustionchambers and draftfines, which extend through all the sections composing said radiators, burners in said combustion-chambers, pipes for conducting off the products of combustion from each individual radiator, pipes 13 leading from the exterior to said OOlDbUS' ti0ncha1nbers, and doors in said pipes 13 and the combustion-chain bers whereby said doors may be closed when the burners are in operation to assist the heating system, and said doors may be opened, when the burners are not in operation, for direct indirect radiation, substantially as described.

5. The combination with a radiator composed of a number of sections, said sections ELUAH M. BOSLEY. lVILLlAM VURDACK.
